Wget Dependencies

Recommended

make-ca-1.13 (runtime)

Optional

GnuTLS-3.8.2, HTTP-Daemon-6.16 (for the test suite), IO-Socket-SSL-2.084 (for the test suite), libidn2-2.3.4, libpsl-0.21.2, PCRE-8.45 or pcre2-10.42, and Valgrind-3.22.0 (for the test suite)

Installation of Wget

Install Wget by running the following commands: 

./configure --prefix=/usr      \
            --sysconfdir=/etc  \
            --with-ssl=openssl &&
make

To test the results, issue: make check.

Some tests may fail when Valgrind tests are enabled.

Now, as the root user: 

make install

Command Explanations

--sysconfdir=/etc: This relocates the configuration file from /usr/etc to /etc.

--with-ssl=openssl: This allows the program to use openssl instead of GnuTLS-3.8.2.

--enable-valgrind-tests: This allows the tests to be run under valgrind.
